I gave a talk at FITC Spotlight Front-End on data visualization.
Data visualization is crucial to understanding the big data being generated by apps and services. Data visualization toolkits such as D3.js and charting toolkits are immensely popular but it remains difficult to create meaningful dashboards or usable analytics tools or clear data visualizations. In this talk, I discussed data visualization principles, presented best practices, showcased excellent visualizations in practice, and shared useful tips and mistakes learned.
